SPECIFICATION forming part of Letters Patent No. 299,012, dated May 20, 11884.

Application filed July 23, 1888.

To all whom it may concern.-

Be it known that we, FREDERICK A. RING- LER and EMIL J. ALFELD, both of the city, county, and State of New York, and citizens of the United States, have invented certain new and useful Improvements in Mortised WVooden Blocks for Electro and Stereo Type Plates, of which the following is such a full, clear, and exact description as will enable others skilled in the art to which our invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Heretofore mortises in electro and stereo type plates fastened on wooden blocks have been made by cutting at one and the same time through both the metal plate and the wooden block the space or mortise required, leaving to the subsequent compositor the work and trouble of j ustifying into such mortise or space, as exactly as is possible, the types requiredto be used therein. Owing, however, to the extreme difiicnlty, if not impossibility, of cutting mortises by this method with sufficient exactitude, such mortises have almost always been inexact, and the su bsequentjustification of the type has consequently involved the expenditure ofa great amount of labor, care,and time.

The object of our invention is to so make mortises for electro and stereo type plates attached to wooden blocks as to avoid the objections attending the use of mortises made by cutting through both the plate and the wood at one, and the same time 5 and it consists in making the same of the construction hereinafter more fully set forth and described.

In the drawings, Figure l is a plan View; Fig. 2, a reversed View of the same; Fig. 3, a perspective view of the core; Fig. 4, a sectional View on the line of X X of Fig. 2 of the finished plate with the metal collar in position, and Fig. 5 a transverse section on the line Y Y of Fig. 4.

A represents the metal plate; 13, the opening or mortise in the metal plate; A, the wooden block; 0, the opening or mortise in the wooden block D, angular locking-grooves in the walls of the mortise in the wooden block; E, the core, and F the metal collar.

In making our invention we cutan opening or mortise in the electro or stereo type metal (Model.)

I and so as to correspond as exactly as possible with the type to be afterward used therein. We then mark the size of this mortise upon the Wooden block and cut an opening or mortise in the wooden block, somewhat larger in size than that in the metal plate. We do not restrict ourselves to any particular size or ex tent of enlargement of the opening in the wooden block as compared with that of the metal plate; but one-eighth of an inch each way will be found convenient. In the walls or sides of this larger opening or mortise in the wooden block we cut grooves or recesses for the purpose of retaining the metal collar, hereinafter described, in position. This being done, the metal plate is fastened to the wooden block, the two openings or mortises being placed so as to correspond one with the other. A core (shown at E) of the size of the type to be used (and also ofthe opening in the metal plate) is then inserted through the opening in the metal "plate, or otherwise held in position within the larger opening or mortise in the block, thus leaving a space surrounding the same, as shown in Fig. 2. WVe then pour molten metal or other suitable material into this space surrounding the core, filling the same. The metal collar thus formed is allowed to cool or become hardened, and the core then being removed the resulting mortise or space thus left is of the size required for the type to be used therein, and when the superfluous metal is removed from the back the mortise is complete. The metal collar surrounding this final mortise is retained in position by the locking grooves or recesses formed in the sides or walls of the mortise in the wooden block into which the molten metalruns.

If corrections in the plate are expected, the application of a small quantity of lamp-black on the back of the metal plate around the mortise therein will prevent any adhesion of the molten metal thereto and permit of the removal of the plate.

Having thus described our invention, what we claim as new, and desire to secure by Leters Patent, is-

1. An electro or stereo type plate having therein an opening of the size of the type to be used, in combinationwith a wooden block, a portion whereof is cut away and the space plate before fastening the same to the block,

so made occupied by a metal collar having therein an opening corresponding with that in the plate, and forming therewith the mortise for the type, substantially as described.

2. A wooden block adapted to be used with 5 electro or stereo type plates by having therein an opening, within the sides of the walls of which are grooves or recesses, and a metal collar cast in the opening, and retained in po-' sition by the metal projecting into the grooves 10 or recesses, such collar having an opening therein corresponding to the type to be used, whereby the same is made to form a part of the mortise for the type when the plate is attached to the block, substantially as shown and I 5 described.-
